✦ Synopsis

A new procedure to formulate and analyze the free vibration problem of structural-acoustic coupled systems is suggested. The system equations are formulated utilizing the concept of the equivalent mass source. The modal expansion method and a matrix transformation technique are used to solve the system equations to obtain the natural frequencies and modes of the system. The procedure is verified by comparing its result with the exact solution of a one-dimensional coupled system. Parameters dictating coupling effects are also identified and discussed.
